sized nuts.

A further object is to provide anut cracking device that is simple inconstruction, efncient in operation and readlly assembled, ad-

justed and taken apart.

One embodiment of the invention is illustrated in the accompanyingdrawing, in which the figure shows a-perspective view.

The device comprises a base frame or bar 1 which is provided at one endwith a U- shaped clamp loop 1 which is slipped over the edge of a tableand held rigidly in place by the clamp screw 12. The opposite end of thebase bar is'provided with an upstanding post provided at its upper endwith perforated ears to which is hinged one end of the crusher bar 2, asby a belt or rivet, the hinge joint being designated by referencenumeral 3.

Projecting from the U-shaped loop is a lug or arm 10 which is providedwith perforatedspaced apart ears between which is pivoted the lower endof the operating handle 4. At a suitable distance from the joint are aseries of adjusting openings 11 within which the lower end of a link 5is pivotally secured by suitable means, such as a bolt 6 or upsettingthe end of 5 which may be extended through one of the openings 11.

The upper end of the link is also secured to the free end of the crusherbar as by a nut 7 An arcuate guide 8 extends upwardly from the bar orframe 1, its upper extend ing through a curved opening in the crusherbar 2, keeping the crusher bar in line at all positions during thecrushing or cracking operation.

A compression spring 9 surrounds the guide post 8 between the base frameand the crusherbar. This spring 9 functions to hold the crusher bar tothe normal inactive position, and closes during the operation ofcracking but with a yielding pressure on the parts so that there islittle the parts being broken.

or no danger of As before stated, 11 are extra holes in op eratinghandle t, for the purpose of adjusting machine for longest nuts, byconnecting 5 to 4, at 11 in place of 6, as shown in illustration. 13,13, 13, are countersunk holes co for putting ends of nuts in to hold inposition on frame 7 while cracking. There are also countersunk holes inbottom side of crusher-bar 2, indicated by dotted lines at 14, 15, 16,which correspond with 13, 13, 13, enabling operator to use whichever setof holes is the right distance apart for different length pecans withoutadjusting the machine. 17, 18, 19, show the different places the pecansmay be put in the machine. The dotted lines show the position of pecanwhen in machine.

In operating the device the nut having been placed upright orlongitudinally in the appropriate countersinks in the base frame andcrusher bar, the upper end of handle 4 is forced outwardly anddownwardly away from the machine, whereupon through the link 5, thecrusher bar will be forced clownwardly compressing spring 9 and crackingthe nut shell away from the kernel of the nut which is left whole orunbroken, the crusher bar having a yielding pressure. Upon releasing thehandle the spring 9 eX- pands and forces it up to inactive position,whereupon the operation may be repeated.

.By my novel construction and arrangement of parts I am able to producea nut cracking machine that is simple, eflicient and inexpensive toproduce, the parts being removable and replaceable.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A nut cracking machine comprising in combination a base bar having astandard at one end, and a U-clamp at its opposite end, a crusher barpivotally connected at one end to said standard, a perforated lugprojecting from the clamp end of the base bar, a handle 199 pivotallyconnected at its lower end to said lug. said handle having a pluralityof adjusting elements. a link pivotally connecting the free end of thecrusher bar with the handle by said adjusting elements, said base barand crusher bar provided with a D111". ralitv of opposing sockets toreceive and longitudinally center various sized nuts, a guide postprojecting upwardly from the base bar, and through an opening in thecrusher bar, M9

and a compression spring mounted on said guide post and between the basebar and crusher bar.

2. A nut cracking machine as defined in claim 1, the guide post beingarcuete, and a compression spring being a coiled spring surrounding theguide post and bearing at its upper and lower ends against the crusherbar and base bar respectively to force the crusher bar to inactiveposition, and to pro- 10 vide a yielding pressure during the nutcracking operation.
